            Bug ID: 45369
           Summary: Missing symbols when llvm is build with LTO
           Product: libraries
           Version: 10.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org
          Reporter: kloczko.tomasz at gmail.com
                CC: craig.topper at gmail.com, llvm-bugs at lists.llvm.org,
                    llvm-dev at redking.me.uk, spatel+llvm at rotateright.com

I've build my own llvm packages using gcc 10 from Fedora rawhide.
That package is with LTO optimised.

When I've installed my own llvm I found that now I cannot build mesa because
some symbols are missing during linking mesa
